Damn that was easier than I thought! First place I looked.


CG range - 100-105mm measured from the LE of the wingtip. Ideal CG is at 103.5mm

Rates -

Ailerons - High 40-45 degrees up/down low 15-20 degrees
Rudder - Max (until it hits the elevator)
Elevator - High 45 degrees up/down low 15-20 degrees

I probably have the throw guage for mine somewhere, and a few others bits and peices. Yell out the next time we are in the same spot and ill bring it all with me.

I may have the manual for my old one somewhere. Ill have a hunt

CG is not massively critical on the addiction, it doesnt have any bad behaviours if its on the piss (just gets really pitchy). I once banged a 4200Mah 3S in mine, just for a giggle, didnt even check the CG

Congrats on the Addiction, its a wicked flying plane, I want another one

Punishment for flying in circles should follow these lines. This is so funny!

WARNING - EXPLICIT LAUNGAUGE

Well if it's a linear BEC you're wasting half that pack in heat for a start. - Linear BEC's are so 2007

You've also added another "point of failure" to your system and of the UBECs I've tested so far, not one has actually met the specifications published for it -- so that 3A UBEC will probably shut-down if you get a stalled servo or even a couple of stiff linkages plus some aerodynamic loads. Flight Pack + UBEC = 2 points of failure. Flight Pack + Life Pack = 2 Points of failure

If you over-discharge the lipo it's toast (A123s will simply take a fresh charge with no worries). - Lipos have a higher energy density than an A123 (in can construction) so for the same size/weight you can fit more Lipo MAh, reducing the chance of over discharging anyway.

If you dork it hard enough, the battery may catch fire (A123s don't do that). If you dork your plane hard enough to set a lipo on fire, the plane is likely so Bleeped that the best idea for it is a fire anyway.

A lipo has about 200-300 charge/discharge cycles in it -- an A123 is good for five to eight times as many. A modern low C rated lipo running at naff all current draw as a Rx pack, properly stored and charged should last 500+ cycles easy

There are lots of reasons why A123s are a far better option than a lipo/regulator setup. There are some difference between the two, but LOTS might be an exageration

If it was possible to plug a little doofa into your slimers gas tank and run your rx directly off that, im sure you would!

I like those little 3A turnigy jobbies, used them in heaps of stuff and never had a problem, but I have never tested them

Be interested in seeing a test on those RCMR, and the CC10A SBEC too (similar size)

BTW Highest servo current draw is usually seen when travel is reversed, ie full one way then bang full the other way. Stall current is usually around half that.

Used to know a guy in Aussie building a Cri Cri. The joke was what you gonna do when you finish your Cri Cri? Die Die!

New choice Idea! VTO fan wing haha.

Patented. Not.

Be cool to try a fan wing PBF. I remember seeing a model of it but cant find it now. Seemed like a really cool idea. Coro would be the perfect material for the wing and the fan too.

Something like this beautiful drawing (wing profile)

So the colombine harvester bit in the middle creates lift as well as propulsion, without the need for much fwd airspeed.

Nah, time to buy higher C packs

SPC works awesome as it sends ya pack voltage via telemetry too, so its double win. Makes low voltage reboots voltage a moot point, as if im sagging my 22V Lipo down to 3.5V (or whatever) ive got bigger problems than an Rx reboot. Ie its likely on fire....

Still amazes me that some people on the Hitec thread dont use the SPC.

Do the HV frisky Rx have an SPC function similar to hitecs optimas?
